I've been hunting around here and on google for an answer to my question by alas have found nothing as of yet.
What I'm trying to do is firstly decode some PWM Serial Data sent from one device to another, however it's operational range is 0-12v. It's in an automotive environment. Is this possible?
Ideally then I'd like to turn it around and replace one of those devices with an Arduino. Essentially the reverse of before, again is it possible?
I'm fairly certain it is possible, not 100% sure on the hardware side of it though. I've found things like the MAX232 which "might" be useful but I'm not sure.
Any help would be greatly appreciated.
